Referring more particularly to the drawings, A, The objects of the invention are to provide a designates a rail or tie plate as a whole, and B, simply constructed, durable and reliable rail a rail section seated therein. The plate A, is chair that can be readily manufactured and formed from rolled plate, malleable iron, steel placed on the market in quantities at comparacastings or other materials and has integral l0 tively low cost. therewith a permanent transversely extending Another object is to provide a rail chair fashwall or shoulder 10, formed to abut the edge 11, ioned from any suitable material, rolled plate, of the rail base C, and then bent to overlap, in malleable iron or steel castings and other matespaced relationship thereto, the top surface 12, rials. of the rail base, as at 13.

The stem portion is provided with a Fig. 2 is a top. plan view showing the locking h le p s way having formed therein a key in dotted lines, in position. projection 29, (see Fig. 2).

The locking pin 22, is so bent intermediately' that once it is driven home any. attempt to tamper with it will cause it to breai: or" split.

The locking pin or key 22, is made of spring steel or other suitable material andis inter mediately offset, as at 25, one end being straight and the other end being outwardly bent, as at 26, to abut against the member 18, and auto matically resist tipping of the same inoperation and thereby retaining this member in balanced, spring securing position relative to the base C, of the rail. Furthermore, when the member 22, is inserted and driven by the fob lower 31, into the shoulder 14, and through the member 18', it will automatically, being of spring steel or other suitable material, partially straighten out past the projection 29, to protrude, becomingself-locking as it is driven home, and through the bent end, impinging on the outer surface of the securing or railholding coming displaced when locked in engagement with-the projection 29-.

Various modified forms of this locking mem her, which it should be noted can be used with the construction disclosed in my previously cited co-pending United States applications, as shown in the accompanying drawings, Figs. 5' to 10- inclusive; but it will be noted that the offset formation 25", is substantially preserved in each of them.

With regard to the walls or shoulders 10, and 14, it should be mentioned that the formationof the latter materially facilitates the insertion of the rail section onto the bearing surface or chair portion 16, into loose engagement with the permanent wall 10, and that when this is ac= complished it is only necessary to insert the securing member in the opening 17', and then insert by means of the follower 31, the selflocking pin or key 22, as previously described, when the operation of placing the rail in the chair and automatically and resiliently looking it in a secure position therein, is accomplished. To further facilitate the locking of the member 18, in the shoulder 14, the passageway'21, may also be varied. Once the locking member 22*, has been inserted it is practically impossible to remove it exceptv with the follower.-"

Referring to the several modified forms of the locking pin or key 22", as disclosed. In Fig. 6, the offset portion 25, is still preserved while the outwardly bent end 26, is extended over the member 18. In Fig. '7, as shown, the bent end 26, engages with a slot or recess in the member 18, or, as shown in Fig. 5, impinges against said member. In Fig. 8, the member 22, is curved and in Fig. 9, it is shown as slightly offset and with one end bent substantially at right angles, as at 28,while in Fig. 10, the looking member 18, is Wedge-shaped. This member 22, and the various modifications thereof is adapted to be used in the construction disclosed in my co-penoling United States applications, as wellas in the present construction, the construction as a whole having been conceived and developed to provide a combined anti-tipping, tamper-proof key or pin in combination with the wall of a rail chair having a rail holding member therein. 7

I From the foregoing itwill be seen that applican-t has'provided combined anti-tipping and self locking means for a rail holding or retaining member, of simple and durable construction that through loose engagement with the tie plate and the rail base, while engaging with and conforming to the contour of the bent wall, all combined with the self-locking means, provide i' o'r flexibility and resiliency in operation with limitation of rotation tending to resist tipping of the retaining member while permitting in combination with the loose engagement of the railwitli the other bent wall,- free wave motion of the rail. In short, the combination with an inwardly hooked rail. retaining wall 10, and an. outwardly hooked rail'abutting wall 14, a detachable rail retaining nieml'oer conforming to the contour" of the outwardly hooked wall andiloosely engaging with. the plate, of a spring pin: or key formed for self-locking. engagement with the abutting Wall 14-, and the retaining member 18, and also impingingv upon said memher in anti-tipping. engagement therewith v The complete operation is as follows:v The combined rail-plate and chair member A, having been secured in position, therail section- B, is lifted into engagement with the abutting wall 14-, and allowed to glide onit onto the; bearingsurfa'ce or chair portion 16,. when it is moved. therealong engaging with the: wall 10-, in

The member 18, is then -placediin-the hole 17, and the locking. pin'18, inserted. by means of the follower 31, in'the guideway 24, of. the wall: or shoulder 14,.and through the opening 21, and asv it. travels it looks, and as, it does, the bent end either impinges on: or otherwise, in any suitable manner, engages with, as illustrated, the outer surfaceot' the holding member 18, acting as a lever to perform the additionalfunctions of resisting-tipping orrotation of the holding member. To withdraw the member 22, it is necessary to use the follower.

A feature of this locking member is. that the base of a rail and in spaced relation thereto.

Various forms of the apparatus described will suggest themselves to those skilled in the art; it is, therefore, not intended that the present application should be limited to any particular form of construction; modifications may be made in the apparatus above described within the scope of the claims, without departing from the spirit or scope thereof.

What I claim for my invention is:
